Django与coverage的结合

1.首先我们编写一个简单的测试用例

from django.test import TestCase


 
def division_funtion(x, y):
    return x / y
    
class AnimalTestCase(TestCase):
    
    def setUp(self):
        pass
        
    def testCase1(self):
        print(1)
    
    def testCase2(self):
        division_funtion(1,2)
    
    
    def testCase3(self):
        division_funtion(1,3)

用python manage.py test启动它进行测试

结果大概是这样的

L:\test\HelloWorld>python manage.py test
Creating test database for alias 'default'...
System check identified no issues (0 silenced).
1
..E
===========================================================
ERROR: testCase3 (HelloWorld.test.AnimalTestCase)
-----------------------------------------------------------
Traceback (most recent call last):
  File "L:\test\HelloWorld\HelloWorld\test.py", line 21, in
    division_funtion(1,0)
  File "L:\test\HelloWorld\HelloWorld\test.py", line 6, in
    return x / y

2.然后coverage上场。

首先是安装

pip install coverage

然后测试

coverage run manage.py test

于是乎我们会得到一个小报告

L:\test\HelloWorld>coverage run manage.py test
Creating test database for alias 'default'...
System check identified no issues (0 silenced).
1
...
-------------------------------------------------
Ran 3 tests in 0.000s

OK
Destroying test database for alias 'default'...

如果想直接看到报告可以用report指令

L:\test\HelloWorld>coverage report
Name                     Stmts   Miss  Cover
--------------------------------------------
HelloWorld\__init__.py       0      0   100%
HelloWorld\settings.py      18      0   100%
HelloWorld\test.py          12      0   100%
HelloWorld\urls.py           3      0   100%
manage.py                    9      2    78%
--------------------------------------------
TOTAL                       42      2    95%

我们还可以用html显示出来

L:\test\HelloWorld>coverage html

会在项目下面生成html文件

然后咱就打开来看看

点进文件还能看到每个文件的覆盖率

整合到sonar里面，可以用一个绝对路径试一下

sonar.python.coverage.reportPaths=/opt/test_proj/coverage-reports/coverage.xml
